摘要：The purposes of the research were to know the influences of crop organicmatters to diversity of soil mesofauna and macrofauna underparaserianthes’ stand (Paraserianthes falcataria), rate of organic mattersdecomposition, as well as the relationship between the rate of organicmatters decomposition and diversity of soil mesofauna and macrofauna.The framework of thinking of this research was the crop organic matterswhich were given to the soil would influence the soil mesofauna andmacrofauna diversities. The presence of soil fauna would help thedecomposition process of organic matters which fertilize the soil. Thisresearch was established under paraseanthes’ stand, with 7 treatments ofcrop organic matters, i.e. cardamom, pineapple, cocoyam, cardamompineapple,cardamom-cocoyam, pineapple-cocoyam, cardamom-pineapplecocoyam,and the treatment without crop organic matters (control). Thesampling of mesofauna data used soil extraction “Barlesse-Tulgreen”method, meanwhile the macrofauna data were obtained from “Hand-Sorting” method and “Fill-Trapp” method. The sampling of decompositionrate data used Pudjiharta’s method (1995). The data which have beenobtained were analyzed by using Analysis of Variance (ANAVA) andcontinued with DMRT test. The Correlation test was done to find out therelationship between the rate of decomposition of crop organic matters andthe soil mesofauna and macrofauna diversities. It can be concluded that theapplying of crop organic matters influenced the soil mesofauna andmacrofauna diversities. The highest coefficient value index of soilmesofauna diversity was 1.36 by using cardamom-cocoyam organic matters.The highest coefficient value index of the soil macrofauna diversity was1.11 by using pineapple organic matters. The highest coefficient value indexof macrofauna diversity on the surface of the soil was 1.27 by usingpineapple organic matters. The crop organic matters of cardamom-cocoyamhas the highest coefficient value decomposition rate, was 0.45. The croporganic matters of pineapple has the lowest coefficient valuedecomposition rate, was 0.15. The relation between the decomposition rateof crop organic matters and the soil mesofauna diversity index, themacrofauna in the soil, and macrofauna on the surface of the soil show thenegative correlation, with the correlation coefficient value, were -0.01; -0.30;-0.001.
